Chapter 1 Introduction 1.5 Ways to Manage the LTE Device Use any of the following methods to manage the LTE Device. • Web Configurator. This is recommended for everyday management of the LTE Device using a (supported) web browser. • FTP for firmware upgrades and configuration backup/restore. 1.6 Good Habits for Managing the LTE Device Do the following things regularly to make the LTE Device more secure and to manage the LTE Device more effectively. • Change the password. Use a password that's not easy to guess and that consists of different types of characters, such as numbers and letters. • Write down the password and put it in a safe place. • Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password to access the Web Configurator, you will have to reset the LTE Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the LTE Device. You could simply restore your last configuration. Keep in mind that backing up a configuration file will not back up passwords used to set up VoIP. Write down any information your ISP provides you. 1.7 LEDs (Lights) The following graphic displays the labels of the LEDs.
